2. Claims.

This invention relates to cartons, boxesor trays constructed frompaperboard, cardboard, fibreboard and other materials of a like orsimilar nature and is adapted for various and sundry uses as, forexample, the packaging, shipping and display of merchandises includingcandy, chewing gum, and so forth.

One of the objects of the invention is to provide an improved form oftray or box of light and inexpensive yet strong and relatively rigidconstruction so that it may offer relatively long resistance to injuryor destruction of itself and contents even though it be roughlyv handledin use.

Another object is to provide a tray or box which may be manufacturedfrom a single sheet of material and wherein all of the parts areintegrally formed thereby to reduce the quantity of material needed, thetime involved and the operations to be performed in the construction,the construction and arrangement of parts being such that the amount ofwastage of material is minimized.

Another object is to provide an improved container construction and acorner construction of such character that they lend relatively greatstrength and rigidity to the box or tray even if the same be composed ofthin sheet material, thereby offering protection to the box or trayagainst damage or distortion as well as protecting the contents.

Still another feature of importance resides in the arrangement of thereenforced sides having relatively smooth edges with a minimum ofexposed raw edges of the material.

A further object is to provide an improved manner of effecting suchreenforcement whereby to obtain the strength and rigidity desired in theconstruction, to provide smooth interior corner surfaces, to provide anattractive as well as useful article of the character mentioned, and toprovide a container within which commodities may be packed for shipment,in which they may be displayed effectively, and from which they may bedispensed directly.

Many other objects as well as the advantages and numerous uses of theinvention will be apparent from the following description and claimsread in conjunction with the drawings, in which:

Fig. l is aperspective view of a present preferred form of the inventionas embodied in a i tray for the shipment, storage, counter display anddispensing of commodities such as chewing gum and candy in smallpackages.

Fig. 2 is a view of a fragment of the tray shown in Fig. 1 but on alarger scale and with portions broken away and other portions displacedfrom their normal positions the better to illustrate certain details ofconstruction.

Fig. 3 is a sectional view taken transversely of a corner of the tray onthe line IIIIII of Fig. l, and I Fig. 4 is a plan view of the tray inblank form, one portion being broken away and some portions being foldedto an intermediate stage of construction, the better to illustrate theconstruction and forming.

The invention may be described conveniently by referring initially toFig. 4 and the blankedout rectangular tray it shows. Struck from asingle sheet of material the blank is out and scored to provide arectangular bottom panel or wall 5 to each of the marginal edges ofwhich are integrally attached side walls or panelsof which two aregenerally and as a whole designated 6 and the other two similarlydesignated 1, these side walls or panels being differentiated from Wall5 by score or fold lines 8 and 9 respectively. Each side wall 6 iscomposed of three portions namely, a first portion H which is to providethe outside wall surface at that end of the tray andwhich portion isdirectly connected to and coextensive with the edge ofthe bottom wall 5,a second portion l2 which is to form a reenforcing flap and which isdirectly attached to the portion ll along a score or fold line [3, and athird portion M which is to form a part at least of the inner surface ofthe wall and which is also directly connected to the first portion alongaligned score lines l5, second portion I2 being out free from bothportions H and M along the full line designated Hi. It should be notedthat while the portion M i substantially coextensive with portion II,its end margins Ma are cut back slightly from the corresponding marginsof the portion H for a purpose that will appear.

The side walls or panels I are similarly constructed in that each has'afirst portion [1 corresponding to portion II, a second portion 18corresponding to portion l2 and joined to portion ll along a score lineI9, and a third portion 2| correspondingto the'portion M and joined toportion I! along aligned score lines 22, the portion, is being out freefrom portions l1 and 2| along the solid or full line 23. Also the endsof portion 21 are cut back as are the ends of portions it. However, sidewalls I difier from side walls 6 in that each at each of its ends isprovided with a pair of end flaps designated 24 and 25, flaps 24 beingout free from side walls 6 and being attached to portion ll along scoreline So the tray or box is set-up into tray or box shape,.

the entire end edge including the projection 26 of each end of a portionl2 will conform to, interlock or inter-fit with and substantially abutagainst the complementary end edge including the notch 21 of theadjacent flap 24. This arrangement is particularly well illustrated inFig. 2, from which it is apparent that the interlocking abutment ofthese parts adds materially to the strength and other features of theconstruction.

In setting up the box or tray from its blank form the portions l2 and I8may be folded inwardly and downwardly and secured, as by adhesive 28,.inface to face relation against and to the inner faces of the respectivelyadjacent portions 11 and IT as clearly shown in Figs. 2 and 4. The freelongitudinal edge of each portion I2 is arranged, in the illustratedembodiment, to lie substantially parallel to and along or closelyadjacent to the adjacent score or fold line 8, and, similarly, the freeedges of portions l8 are arranged to lie along or close to the'score orfold lines 9. -Thenext step in the operations may then-be the inward anddownward folding of portions 2| on score lines 22 to overlap and lieupon-the upper (inner) faces of portions I 8 to which theymay be securedas by adhesive 29. At this time the several side walls may be swungupwardly about fold or score lines 8 and 9 and theflaps 24 and 25 (eachflap 25 will then be overlying and against a part of its adjacent flap24) may be folded along score lines 8a and 8b to extend at right anglesto the walls to which they are attached and to lie inside of theportions H of the other-side walls and to positions where the outer endedges of flaps 24 abut against the complementarily formed end'edges ofportions 42. The flaps 24 and 25may be secured to one another byadhesive and, similarly, the flaps 24 may be secured to the inner facesof portions I I. Thereafter the portions l4 may be folded about scorelines. l5 and .inwardly and downwardly to overlie the inwardly facingsurfaces of portions l2 and flaps 24 and 25, adhesive being appliedappropriately to secure thes parts in their'folded positions. 7

It will be appreciated that the cutting away or notching vout of theends ofportions l4 and 2| to reducetheir overall lengths at each end ofeach is for the purpose of permitting these ends to clearone anotherwhen the tray is folded into its final shape, that is, so that theadjacent ends of portions I4 and 2! at the tray corners will notbindorbe distorted in the folded form. While in theillustratedembodiment of the invention both ends of both portions l4 and 2| havebeen shown as cut back or notched, it is to be understood that this maynot be wholly necessary as thepurpose may be served if only one of apair of portions l4 and2l (one end of a portion l4 or one end of aportion 21) at a corner is notched "strength of the material employedand a product that will retain its shape and protect its contents evenunder particularly heavy or intense abuse. 'Besides these resultingfeatures the box 7 or tray is neat and attractive in appearance for theedges and corners are smooth and all raw edges are concealed or fall inthe least conspicuous places and where there is the least chance oftheir becoming frayed and unsightly in use. In addition the castellatedor raised corner construction makes a very effective counter displaydesign for a box or tray for candy and chewing gum and the like andpermits the contents to be observed yet easily dispensed. Otheradvantages are easily appreciable. It is of course relatively immaterialwhether the box or tray be rectangular or that its sides be equal orunequal for the invention-is applicable to boxes having a greater orlesser number of sides and whether the sides are equal or unequal inlength. Furthermore the flaps 24 and 25 may be arranged so that eachwall has but one pair of such flaps, the flaps, being disposed at thecorresponding end of each wall, and, if desired the flaps 25 may beentirely omitted.

The invention being applicable to other types and forms of boxes andtrays, and not being of such character as to confine its use to the boxor tray chosen for illustration and description herein, we-desire to belimited only by the invention spirit as embraced within the scope of theappended claims.

We claim: 7 v 1. In a tray having a bottom panel and at least oneupright side wall, the improvement which comprises, in combination, aside wall having its maximum height adjacent its ends and a portionintermediate its ends having a depressed upper edge, a finishingreinforcing flap integrally joined to said side wall folded inwardly anddownwardly upon score lines determining said maximum height, saidreinforcing finishing flap having a portion cut from the materialthereof whereby no part thereof extends beyond the'bounds of itsassociated side wall, and a second finishing flap integrally joined tosaid side wall along a score line defining said depressed edge andincluding all of said portion cut from said first-named finishing flap,said second finishing flap being engaged between said side wall and saidfirst-named finishing flap and secured thereto by means of adhesive.

2. A rectangular tray having a bottom panel and four upright side wallsas defined by claim 1, one pair of oppositely disposed side walls havinglongitudinal extensions secured by adhesive between the others of saidside walls and their associated reinforcing finishing flaps.
